Pregnant Woman with Atypical Hemolytic Uremic Syndrome Delivered a Healthy Newborn under Eculizumab Treatment

Pregnancy-associated thrombotic microangiopathy is a very rare condition; however, it significantly increases fetal or maternal morbidity and mortality. Pregnancy may trigger atypical hemolytic uremic syndrome (aHUS) or thrombotic thrombocytopenic purpura. The risk for pregnancy-associated aHUS is highest during the second pregnancy. The outcome is usually poor with 50 –60% mortality; renal dysfunction and hypertension are the rule in those who survive the acute episode. After the development of complement regulation mechanisms and aHUS pathogenesis, eculizumab has been widely used as a first-line treatment in aHUS. Eculizumab has been produced to minimize immun ogenicity and Fc-mediated functions, including recruitment of inflammatory cells and complement activation, and using eculizumab in first-line treatment improves kidney function. Recent studies showed that early diagnosis and rapid use of eculizumab in first-line treatment improve outcomes. We demon strate a case with pregnancy-triggered aHUS occurring in the second trimester, who was successfully treated and delivered a healthy baby under eculizumab treatment.Case Rep Nephrol Dial 2016;6:143 –148
